XMM-Newton Observations of Two High-Redshift Quasars: RX J1028-0844 and BR 0351-1034
(IOP Publishing, 2004)
We report the results of XMM-Newton observations of two high-redshift quasars, one radio-loud, RX J1028.6-0844 (z = 4.276) and one radio-quiet, BR 0351-1034 (z = 4.351). We find that the evidence for strong excess absorption ...
Discovery of a Jetlike Structure at the High-Redshift QSO CXOMP J084128.3+131107
(IOP Publishing, 2004)
The Chandra Multiwavelength Project has discovered a jetlike structure associated with a newly recognized QSO at redshift z = 1.866. The system was 9farcm4 off-axis during an observation of 3C 207. Although significantly ...
The Chandra Multiwavelength Project: Optical Follow‐up of Serendipitous Chandra Sources
(IOP Publishing, 2004)
We present follow-up optical g', r', and i' imaging and spectroscopy of serendipitous X-ray sources detected in six archival Chandra images included in the Chandra Multiwavelength Project (ChaMP). Of the 486 X-ray sources ...
